Abstract

La présente invention concerne un dispositif d'étalonnage apte à effectuer simplement et rapidement une opération d'étalonnage en vue d'améliorer la précision et la fiabilité d'une valeur mesurée par un dispositif d'analyse de composé gazeux, et un dispositif d'analyse de composé gazeux comprenant ledit dispositif d'étalonnage. À cet effet, le dispositif d'étalonnage de la présente invention est un dispositif d'étalonnage permettant d'étalonner un dispositif d'analyse de composé gazeux qui détecte, par un détecteur, un composé d'un échantillon gazeux, séparé en tant que composé unique par l'intermédiaire d'un tube de séparation, et analyse ledit composé, le dispositif d'étalonnage étant relié à un tube d'alimentation permettant de fournir un gaz au tube de séparation, de façon à fournir séquentiellement une pluralité de gaz d'étalonnage possédant des concentrations différentes au tube de séparation par l'intermédiaire du tube d'alimentation.
